Adaptive model and the adaptive mechanisms for thermal comfort in Japanese dwellings

Nepal is a landlocked country with geographic variations that have led its people to develop a variety of distinctive cultures. Part of these cultures is reflected in the way that people create a suitable indoor thermal environment in residential buildings, depending on the outdoor climatic conditions . Temperature preferences may vary depending on the local climate characteristics. The aim of this study was to investigate the clothing adaptation of Nepalese residents in traditional houses during the winter. The indoor thermal conditions were examined during a winter in three regions of Nepal with different climates, including cold, temperate and sub-tropical climatic regions. A set of thermal measurements and thermal comfort survey was conducted in traditional houses of selected villages in Mustang, Kavrepalanchok, and Sarlahi districts during the winter of 2016. As part of the survey, 275 votes were collected, while the indoor and outdoor thermal conditions were being recorded in 108 houses. The mean indoor globe temperature was 12.2 °C in the cold region, which was 4.7 °C and 10.0 °C lower than that in the temperate and sub-tropical regions, respectively. The estimated mean comfort globe temperature was 13.8 °C in the cold region, which was 4.1 °C and 9.3 °C lower than that in the temperate and sub-tropical regions, respectively. The difference in the regional comfort temperature is quite large, and this is considered mainly due to differences in the adaptive behavior and particularly the clothing adaptation of the residents in these distinct climatic regions. The mean preferred temperature in the cold region was 14.7 °C, which is slightly higher than its mean comfort temperature. The mean clothing insulation was 1.63 clo in the cold region, and 1.32 clo and 1.15 clo in the temperate and sub-tropical regions, respectively. The choice of clothing and its insulation properties during the winter were mainly based on the condition of the building, indoor and outdoor climatic conditions.

A field investigation on the wintry thermal comfort and clothing adjustment of residents in traditional Nepalese houses

In order to investigate the thermal comfort, quality of sleep and behaviour of the occupants of Japanese bedrooms in the hot and humid season, we have measured the air temperature and relative humidity in the 26 bedrooms of 10 houses, and conducted a thermal comfort, depth of sleep and occupant behaviour survey with 31 residents, obtaining 1176 votes. The mean indoor air temperature in the rooms during the survey period was 26.3–27.9°C. The residents sleep in the bedrooms, where the indoor air temperature is high. The mean comfort temperature is 26.4–27.1°C. The thermal comfort of residents is high and the depth of sleep is normal for the given thermal environment. The results showed that residents are thermally satisfied and slept well in the bedrooms using various thermal adjustments, such as cooling, fans, windows and clothing insulation.
